Issues with FOV

I noticed on PC when using lower field of view(FOV) such as 78, the frames are more choppy, it is harder to properly aim, and adjusting settings for mouse and keyboard will save you. But when I turn the FOV up to 120, visually it is a lot more crisp, I can actually aim properly, and can even begin to play with higher sensitivity. Its basically higher field of view of -Yoink-.
